ADJUSTMENTS
Adjustable stationary vise
The adjustable stationary vise is located at the rear of your cut-off
machine. This vise can be rotated to attain cutting angles from 0
45
0
and moved backwards to allow greater cutting widths.
Cutting angle adjustment
To adjust the angle of cut:
1. Using the supplied hex. key, loosen cap screws behind the vise
fence.
2. Rotate the vise fence until the desired angle of cut is aligned with
the indicator groove in the machine base.
3. Check the angle of the vise fence to the abrasive wheel using a
protractor, bevel square, or similar device.
4. Using the supplied hex. key, securely tighten the cap screws
holding the vise to the machine base.
Moving the stationary vise
To increase the width of cut of the cut-off machine:
1. Using the supplied hex. key, remove cap screws securing the vise
to the cut-off machine base.
2. Reposition the curved slot of the vise base with the most rear
threaded hole in the machine base and install a cap screw in this
hole. DO NOT OVERTIGHTEN.
3. Align the remaining vise bolt hole with the middle threaded hole
in the machine base and install a cap screw.
4. Check or adjust the cutting angle and securely tighten both cap
screws with the supplied hex. key.
Quick lock-release vise
The cut-off machine is equipped with a quick lock-release vise
system as standard equipment. With this feature you are able to open
and close the vise quickly without repetitive turning of the vise crank
handle.
Using the quick lock-release vise. To loosen:
1. Slightly release tension on the vise by rotating the crank handle
counterclockwise 1/2 to 1 turn.
2. Lift up the quick lock-release lever and pull back on crank handle
to slide open the vise.
To tighten:
1. Push the crank handle forward to slide the vise against the work
piece.
2. Push down on the quick lock-release lever to engage its threads
with vise screw.
3. Rotate the crank handle clockwise to tighten the vise against the
work piece.
Adjustable positive depth stop
The adjustable depth stop is threaded into the base of the machine at
the rear. By raising and lowering the depth stop bolt with a wrench
you can control how far the abrasive wheel travels when the machine
handle is depressed.
ADJUSTMENTS & OPERATION

OPERATING
Before operating the cut-off machine, check the power supply and
make sure it meets the requirements listed on the nameplate. A
substantial voltage drop will cause a loss of power and machine
overheating. Common causes of power loss and machine overheating
are insufficient extension cord size and multiple tools operating from
the same power source.
Switch
To start the tool, completely depress the safety button and at the same
time press the trigger switch both located in the operating handle. To
stop the tool, release the trigger switch completely.
Cutting
WARNING: Do not attempt to cut wood or masonry with this
machine. Never cut magnesium or magnesium alloy with this tool.
Failure to comply with this warning could result in serious personal
injury.
1. Secure the tool in place to prevent machine movement or tipping
during the cutting procedure.
2. Firmly secure the material to be cut using the machine's vise.
WARNING: Large, circular, or irregularly shaped material may
require additional means of clamping to be secured in place
adequately for cutting. Use "C" clamps and blocks to hold material
securely. Failure to comply could result in serious personal injury.
3. Start the machine by pushing in the safety button and pressing the
trigger switch to allow the cut-off wheel to come up to full speed
before contacting wheel to material.
4. Slowly push down on the operating handle until the cut-off wheel
contacts the material being cut. Use a steady and even pressure to
obtain a uniform cut. Never force the wheel into the material.
5. When the cut is complete, release the trigger switch and allow the
wheel to stop before raising it to the full open position.
DANGER: Do not touch the cut material until it cools down or you
will be burnt! Failure to heed this warning will result in serious
personal injury.
MAINTENANCE
WARNING: Always disconnect the cut-off machine from the power
source before servicing the unit or making adjustments.
Keep the tool clean. Remove accumulated dust and metal particles
from working parts. Periodically check screws and bolts for
tightness. Apply dry lubricant monthly to the points listed to extend
machine service life. Lubrication points:
• Vise screw shaft.
• Front vise clamp rotation shaft.
• Slide way of vise.
Remove the brush caps at regular intervals to check the carbon
brushes. When the brushes are worn to the "standard line", as
indicated on the carbon brush, replace them.
